I'm trying to get my site www.woodriverabilityprogram.org/joomla/ to display the US date format. I have the US English Joomla language installed and Joomla articles are fine but K2 items are still wrong. How do I fix this?

getk2.org/community/New-to-K2-Ask-here-first%21/1644-k2_date_format_lc2-modifying-this-doesnt-work

I tried that link but it says


You do not have permissions to access this page.

Install or modify the K2 US language pack.
